Anthony Johnson is critical of his most recent performance against fellow UFC vet Jake Rosholt, saying he felt “stiff” against the fighter despite knocking him out with a head kick in the second round.

But training with the Blackzilians in Boca Raton, Fla., Johnson said he’s now settled into the light-heavyweight division and isn’t moving anywhere.

In his days as a welterweight, Johnson said he would arrive to the fighter hotel already feeling the effects of a weight cut that forced him to shed in excess of 50 pounds for every fight.

Giving an interview at the Mandalay Bay Resort & Casino in Las Vegas on Thursday, the day prior to his latest weigh-in attempt, he looked anything but miserable.

“I have six pounds to go, and I’m here talking to you and laughing,” Johnson said. “Usually, I’m fatigued already. But now, I don’t worry about that stuff. My mind is clear.”

With fewer of his thoughts consumed by the need for food, Johnson (13-4) can now focus more on the fight head of him, which, in this case, is Bellator veteran D.J. Linderman (14-3). The two serve as the co-main event of World Series of Fighting 1, which takes place Saturday at Planet Hollywood Resort & Casino in Las Vegas. The event’s five-bout main card airs live on NBC Sports Network at 10:30 p.m. ET (7:30 p.m. PT).

Linderman’s fans have actively promoted the fight, Johnson said.

“On Twitter, some of his boys, they tweet me every now and then,” he said. “They said something like Anthony ‘Rumble’ is about to get crumbled. He’s doing good promotion for himself. I’m down with it. I retweet it. I don’t have a reason to talk trash any more. When I was younger, I was spitting all kinds of crazy stuff. But now, I’m older and a little bit smarter.”

In six years as a pro, Johnson made some career moves that, in hindsight, probably weren’t the smartest (though they were probably made under the duress of hunger). Despite a winning record and penchant for knockout wins, he was cut by the UFC after failing to make weight on three occasions. UFC President Dana White recently said he wasn’t opposed to re-signing the fighter, but wanted to ensure he never again came in heavy at the scale.

Johnson remains a marketable commodity and could shake things up in the UFC’s light heavyweight division, where Jon Jones reigns. “Rumble” said he would have filled in for the injured Dan Henderson to fight Jones and save the ill-fated UFC 151. But at the moment, his next step is not his priority.

Getting loose at light-heavy is.

“I haven’t thought about it,” Johnson said. “I get asked that question so much, and I still don’t think about it. I think about what’s in front of me and what I need to do with the company I’m with.”
